The recent gathering of as many as 3,500 people at a religious conference at Nizamuddin in the national capital is threatening to turn the area into the biggest covid-19 hotspot in the country and could trigger a tide of infections in several states.
The central and state governments now face the challenge of pan-India contact tracing and containment as the people at the 13-15 March event have been exposed to those who have tested positive for covid-19.
Of the people who attended the event, 441 are in hospitals and 1,107 people have been taken to quarantine centres, according to the body that organized the conference.
